My questions are: 1. What methods are being used by kvm/qemu/libvirt to reset the GPU on guest shutdown? 2. Is the problem only cuased by the fact that GPU reset is not implemented correctly in the radeon driver of are there improvements that are needed in kvm/qemu/libvirt in order to get this working? -- You are receiving this mail because: You are watching the assignee of the bug.
